摘要
Abstract
In the use of infrared remote control equipment , equipment stability and regulation smoothness are the most basic and the most important index . According to the NEC protocol , an infrared and adjustable amplifier system based on STM32F103C8 is designed . This system captures the pulse signal of infrared remote control transmitter through the STM32F103C8 input port , and its powerful timer is used to decrypt remote control code , determining which judgment function keys is pressed . Function keys are pressed to drive SCM GPIO port to output control signal to adjust digital potentiometer X9313 . The power amplifier input voltage is adjusted effectually , so that the increase and decrease of the volume are adjusted smoothly . The tests show that power amplifier sys-tem can adjust the volume effectively and smooth through the infrared remote controller .关键词
